121 help
122 This kernel feature is useful for number crunching applications
123 that may need to compute untrusted bytecode during their
124 execution. By using pipes or other transports made available to
125 the process as file descriptors supporting the read/write
126 syscalls, it's possible to isolate those applications in
127 their own address space using seccomp. Once seccomp is
128 enabled via /proc/<pid>/seccomp, it cannot be disabled
129 and the task is only allowed to execute a few safe syscalls
130 defined by each seccomp mode.
131
132 If unsure, say Y. Only embedded should say N here.
